phpmapscript: changing a layer's style

[Dylan Beaudette]

Thanks Aaron,

that did the trick.

We have converted our mapserver app to ka-map, and thus i need to learn some 
mapscript!

However, with your advice I was able to solve this small problem. Doing 
anything interesting with GRASS these days?

Cheers,

Dylan

PS here is a link to our new ka-map application:
